duced.

The bosses 12 and 13 are formed with round 815111 Other h l h attend-ant advah' slightly tapered holes 18 and 19, respectively, tage-s of the lhvehtloh f h pp to into which are driven for a tight fit the round horseshoers and others skilled in the art from tapered ha ks or stems 20 d 21 ti the following detailed description, taken in lyof a pair of toe calks 22 and side calks 23. connection with the accompanying drawings These calks are preferably f th t i htwherein I have illustrated a desirable physiedge type taking the forms clearlyshown-in P cal form or embodiment of the invention Well Figs. 4. and, 6, and presenting straight comof the road or pavement.

By reference to Fig. 2 it will be seen that the side calks 23 are located well rearwardly on the sides of the shoe frame, behind the rearmost of the nailing holes and just in advance of the ends of the pad. This location of the side calks, which I believe to be novel with my present invention, is very advantageous in the Way of preventing both side slip and twisting of the hoof on the pavement.

Side calks, in addition to toe calks, have hitherto been known broadly, but so far as I am aware the side calkshave been located so far forwardly on the sides of the frame as to be of little aid to'the toe calks in preventing side slip or twisting. By reference to F ig. 6 it will be seen that the lowerends of the side calks 23 are substantially flush with the bottom of cushion pad 16, so that the pad and the side calks engage with the road or pavement throughout the rear half of the shoe.

' The described structure of calks and mounting means therefor enables the calks, when unduly worn, to be driven out and readily replaced by new calks, which is a pronounced economy over shoes formed with integral calks; and it also permits the tread edges of the calks to be set at any desired angle. The two toe calks 22 are preferably so mounted that their tread edges will extend substantially at right angles to the longitudinal median line of the shoe, which affords the best toe traction to the animal when drawing a heavy load or climbing a hill. The side calks 23 will preferably be set oblique, as shown by full lines in Fig. 2; but for heavy pulling they may advantageously be set in the same direction as the toe calks 22, a shown by dot and dash lines at the right in Fig. 2; while on icy pavements whereon the animal is liable to slip in any direction, the

side calks 23 will preferably be set substantially parallel with the longitudinal median line of the shoe, as indicated by dotted lines at the left in Fig. 2, so that, while the toe calks prevent forward and rearward slip, the side calks will be equally effective to prevent side slip.

- It has not infrequently been demonstrated, by actual experience, that the horse shod with a shoe having a plain flat frame equipped with toe calks will sometimes strike the toe calks so hard against an obstruction on the road as to bend the fore part of the frame downwardly and pull loose the foremost fastening nails in the hoof. I have also hereinabove referred to the frame as preferably being forged from mild or soft steel. The purpose of this is to enable the same size of shoe to be used on hoofs varying slightly in Width.

If the hoof is too narrow for a good fit, the sides of the shoe frame can be swaged inwardly, and vice versa, if the hoof is slightly too Wide the sides can be swaged apart, both to preventing this, I have provided the reinforcingribs15"ei tending on each side be- 16 affords cushion tread for the rear or most 1 tender part of the animals foot, while the tween the calk bosses 12 and 13. With these reinforcing ribs, mild steel can be used in the manufacture of the frame without any danger of the accidental bending of the lat- 50 ter in service. r a

From the foregoing it will be seen that the invention provides a shoe-well adapted for year-round service. The wide, thick'heelpad four calks afford security against slipping on wet and icy pavements without nullifying the cushioning effect of the heel'pad. The struc-' ture is simple, comprising only six assembled parts, namely, the frame, the pad, and the four calks; and the economy is still further enhanced by the renewable character of the calks. -While s'omeofthe individual structural features of my improved shoe, such as the heel pad and renewable calks, are broadly old and known in other constructions of shoes, I believe that the combinations pointedout inthe appended claims,whereb.y the individual elements and structural features/1 cooperate to produce a better and more efficient and durable horseshoe of the type described, are new and useful.

Ic'laim: i m 1; Ina horseshoe of the type described, the combination of a one-piece full length metal shoe frame. formed with rows of nail-holes in its sides, a heel pad mounted on the under side of the rear end portion'of said frame, a toecalk located on the frontof the frame,

and a pair of side calks respectively located on the sides of the frame between the rearmost nail-holes and the ends of said pad, the shoe having an open center for ventilating the frog of the hoof. Y

2- 'In a horseshoe of the type described, the combination of a one-piece full length metal shoe frame formed with rows of nail-holes in its sides and pad seats in rear of said rows, single heel pad anchored at its ends in'said seats and spanning the space between the latter, a removable toe calk mounted on the front ofthe frame, and a pair of removable side calks respectively"mounted on the sides of the frame between the rearmost nail-holes 12b and the ends of said pad, the shoe having an open center for ventilating'the frog of the hoof. r

3. In a horseshoe of the type described, the combination of a one-piece full length meta iii said rear bosses, a centrally bowed heel pad anchored to an spanning the rear ends of the sides of the frame, and integral stiffening ribs on the under side of said frame in rear of said rear bosses, sa1d ribs bemg located inwardly of sa1d rows of nail-holes and at their ends merged into said forward and rear bosses.
